Otto's Irresistible Dance
From Ardrana
When an Otto's Irresistible Dance spell is placed upon a creature, the spell causes the recipient to begin dancing, complete with feet shuffling and tapping. This dance makes it impossible for the victim to do anything other than caper and prance.
Note: This version of Otto's irresistible dance originally appeared in the 2nd Edition Player's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
